ferent widths depending on the products required. Thus in printingmagazines it may be desired to vary the size of the page of the in'oduet, and in news papers'it may he'desired' to print at one time on a web nine columns wide and at another time on a narrower web, as for instance one eight columns wide. In the production of products on such presses these webs are divided or slitnnd the halves or'the two parts of the divided .web assoeiated in superposed relation to get'tlie prod not desired. In thus assoeiating the webs, the webs pass over certain devices known as turner bars, by which a half or a part of the divided web is turned and brought into correct relation with'the otherpart. .Nhere webs e1" difi'ei'ent widths are to be thus, divided'and associated, it has been necessary to adjust the turnerbars so that the two parts of the webs will be brought into correct position. This adjustment of the bars must be very carefully done and takes up an undes sir-able amount of time, particularly wherea quick change from one width web toanother is desired.

It is the particular object of the present 111- vention to provide an improved arrangement for associating the halvesor parts of divided webs of different widths without the necessity of making any adjustments in the parts so that the press may be easily and quickly changed to print from a web of the desired 7 width.

A further object of the invention is to produce such a construction which shall be of simple form and which can be readily and conveniently installed in the machine.

With these and other objects not specifically referred to in view, the invention consis .s in certain novel parts, arrangements and combinations which will be described in connection with the accompanying drawings and the novel features pointed. out in the claims hereunto annexed.

Referring now to theseidrawings,the pare machine selected to illustratethe invention is afour-color printing andperi ect ing ma-chine, though it will be understood that the invention is intended for and can be used in other types of machines where it isdesirable to Pllfll). on webs of diflerent widths. The web W, from a sui'tablesouree of web supply, notillustrated, is printed on one sideby a pair oi form cylinders 1, 2, inked by suitable inking mechanism 3, 4, and .an

impression cylinder 5.. From this meehanisin the web passcstro'm suitable guide rolls 6 and is printed. on the other-side by two form cylinders 7,8, and an impression cylinder 9, the form cylinders being inked b suitable inkingineeha nism 10,11. If de sired,an offset web 12 maybe associated with i the web to prevent offset during thesecond From the printing couples 8, 9 the web passes over a suitable guide roll 13 to. and between a rolls 14, 15, the slitter 16 being shown as arranged to divide the web centrally.

In accordance with the invention an im proved associating imicha nism is provided whereby the dividedparts or .halves of the web may be. associated in.superposedrelz tion, andthis mechanism is soarranged that webs of diliierent widths mayhave their parts so associated without requiring any'adj'ust ment of the associating mechanism. While this construction may be varied to some ektent, a convenient one is that illustrated. Referring to Figure 2, there is shown a turner bar 17 and a'pair ofturn'er bars 18, 19. In Figure 2 is illustrated-the leadoi two .webs' of different widths. Referring 'first to the wideweb WV, this web is divided into two partsW and W this web being preferably slit through the center into two equal parts,

into two parts'X and X by the slitter 16,

the division being on the center line of the web. One of these'parts, however, asX is led around the turner bar 17 and then around the turner bar: 19 and there assgciated in pair of dividing 0r slitting superposed relation with the part X It will be observed that the bars 18, 19 are so arranged with respect to each other and: to the slitter that the webs come in exact position for superposed relation and it is unnecessary to adjust any the parts of the associating mechanism to obtain this desired and correct registration ofthe' two Webs. Thus a press can be very quickly changed from one size product to another, which is particularly advaiitageousin certain newspaper work where One edition will be run on an eight eolui'i'ni wide web and sueceedii'ig GtlltlOfilOiiiL nine column wide web.

It'wiii be understood, or course,that the width of the webs referred to liave' been se l ect'e'das merely ill'u'strativeof the invention and that the invention can be used with other width webs, and then, oi course, any oft-he barsma :be made adustable if desired;

Furthermore it will be uii'dorstood that the ,z J webs maybe divided at {JOID'JGS' other products, the bars being cor ranged-to propei'ly'associate the divided parts of tliewebs. o

' While the invention has-been shown and de" scribed in its pietf'erred form; it will be under- 7 stoodthat' certain variations and changes i I 1. In a p -intingma hi may he made in the mechanisms shown and described and that such'chaiiges are wit 7 the invention as defined in these appeiided elai ifis. I n o i What I claim is: 1' A j V e, the combination of means for forwarding a 'veb,'means for slitting the web, means for giving one of the parts of the web a quarter turn to'position it for direct association with the other part of the web in superposed relation with'the same'sideiup said Other Part of the web pass- 1 ing" directly through the machine, and a second associating ineans cooperating with the associating means whereby the divided parts of a diflerent width web may be assodated in superposed relation without adjust-.

merit of either associating means.
